Lots of astronomy, cosmology, physics non-fiction! Going cheap! ;)

Are you a fan of astronomy/cosmology/physics non-fiction, or know one?

I have 20+ titles- see pics. Condition ranges from 'well thumbed but complete' to 'almost as new'. I'd like £1 or £2 each for them, depending on condition/size. ????

Buyers can pick-up from me in Litherland (North Liverpool), and, if they like, have a browse before buying.

Otherwise I will deliver around Merseyside for £2, or post at cost.

I'm having a big clear-out of books (and other stuff) at present, see my other ads on here or else ask me for any particular titles, authors or genres which interest you- there is a fair chance I will have something you'd like.
